【発明の詳細な説明】
この発明はフィルの通電によって弁の作動を行なわせる
ようにした電磁バルブに関し、更に詳しくはコイルへの
通電の極性に応じて、弁の反対方向での作動を行なわせ
得るようにしている電磁バルブに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic valve that operates in the opposite direction depending on the polarity of energization to the coil. This relates to the electromagnetic valve that we are trying to obtain.
従来の電磁バルブにあっては、コイルで発生された磁束
が永久磁石を通るようになっている為、その永久磁石の

、その結果、弁を動かす力が小きくなってしまったり、
あるいは永久磁石を通る上記磁束によって永久磁石が逆
励磁され、それを劣化させてしまった抄する欠点があっ
た。In conventional electromagnetic valves, the magnetic flux generated by the coil passes through a permanent magnet, so the magnetic flux is weakened by the large magnetic resistance of the permanent magnet, which causes the valve to move. The power may become weaker,
Alternatively, the magnetic flux passing through the permanent magnet causes the permanent magnet to be reversely excited, resulting in deterioration of the permanent magnet.
そこで本発明は、上述の欠点を除くようにしたもので、
充分な力を発生させることができ、その上永久磁石の劣

。Next, in the electromagnet 2, U is a yoke, which is formed into a cylindrical shape with a bottom and also serves as a case. With 12Fi yaw,
- The bottom plate is configured to be attached to the yoke U to which the case j is attached. 13 and 14 are the yokes 11,
l! Each pole piece is formed into a ring shape. 15 and 16 #i respectively indicate permanent magnets, both of which are formed in an annular shape and are magnetized to have magnetic poles of N and 8 as shown in the figure. 17.
18ij yokes are shown respectively. It is formed to size. η indicates a coil L1, which is wound tightly as is well known. Next, 23 is a connecting rod which is attached to the yokes U and 12 by well-known bearings U and 25 so as to be able to move forward and backward in the directions of the arrows. This connecting rod 23Fi is integrally connected to the spool 9. The attachment is made of plastic and is fixed to the connecting rod with a fixing pin η. In this plunger 26, nine annularly formed magnetic pole portions are shown. Each of the yokes and the plunger is made of a material that is not permanently magnetized, such as soft iron. If and 31tl balance springs, both of which are compression springs, are used to normally hold the plunger I in the neutral position as shown in the figure, and when the plunger force is displaced from the neutral position, the balance spring is This force is used to urge plunger A toward the neutral position.

．ｌｉｔそれぞれシリンダー４に開口する。In this state, the spool 9 also exists in a neutral position as shown in the figure. When a direct current is supplied to the coil η in this all, magnetic flux is generated by the coil as shown by the broken line arrow in the figure. Then, as is clear from the figure, more magnetic flux passes through the opposing surface between the magnetic pole arm and the magnetic pole section 9 and the opposing surface between the magnetic pole piece node and the magnetic pole section, and the magnetic flux passing through the opposing surface between the other magnetic pole piece and the magnetic pole section increases. Since less magnetic flux passes through the plunger 2B, a force is applied to the plunger 2B in the left direction in FIG. 1, causing the plunger 2B to move in the same direction. Then, the spool 9 also moves to the left in FIG. 7 via the connecting rod 2. In the case of an octopus, the spring 31 is compressed, as is clear from the figure. and plunger I
When the plunger I moves to the left until the position where the above-mentioned force (which varies depending on the magnitude of the current flowing through the coil B) and the repulsive force of the togeneda is balanced, the plunger '& stops at that point. As a result, the spool 9 also moves to a corresponding position, and the bow is adjusted according to the moving position of the spool 9)

Note that when the direction of energization to coil B is reversed, the magnetic flux generated by coil η becomes in the opposite direction to the direction indicated by the broken line arrow, so that the plunger station moves to the right in the figure.

In the figure, 32Fi is a cylindrical yoke, and 33 is a plate-like yoke, which functions equivalently to the 11° branch of the yoke in the previous embodiment. 34 indicates a closing body. In addition, this closing condition is formed integrally with the yoke to improve stuttering. -Yoke above! , 33 and the closing body 34F1 are integrally coupled by caulking the ends 32& of the yoke wings.

(Also, the same concept will be used in the next version, and the alphabet f will be added to omit the redundant explanation.) Next, FIG. 3 shows a further different embodiment. In the figure, reference numeral 35 denotes a magnetic pole piece, which also serves as the addition of the two magnetic pole pieces (2) in the example of FIG.

When the coil η is energized, not only can the plunger A be moved in one direction by an arbitrary distance and held at that position, but it can also be moved in the opposite direction by reversing the energization polarity. It has the advantage that it can be held and operated by a desired amount no matter which direction the valve body of the valve device is directed.

When moving the permanent magnet 15., the magnetic flux generated by the coil η moves the permanent magnet 15. Since it is applied to the plunger I without passing through the lft, most of the above magnetic flux can be used to move the plunger, which has the effect of generating a sufficiently large force with a small coil, and the F1 permanent magnet It also has the effect of preventing deterioration of Takumi and 16, allowing it to be used for a long time.
